 Use the CLI to preview your documentation locally as you write and edit. View changes in real-time before deploying, test your documentation site's appearance and functionality, and catch issues like broken links or accessibility problems.
 
 The CLI also has utilities for maintaining your documentation, including commands to rename files, validate OpenAPI specifications, and migrate content between formats.
 
 ## Install the CLI
 
 <Info>
   **Prerequisite**: The CLI requires [Node.js](https://nodejs.org/en) v20.17.0 or higher through v24. LTS versions are preferred.

 ### Custom ports
 
 By default, the CLI uses port 3000. You can customize the port using the `--port` flag. To run the CLI on port 3333, for instance, use this command:
 
 ```bash
 mint dev --port 3333
 ```
 
 If you attempt to run on a port that is already in use, it will use the next available port:
 
 ```mdx
 Port 3000 is already in use. Trying 3001 instead.

+## Skip OpenAPI processing
+
+If you have many OpenAPI files, skip OpenAPI file processing during local development to improve performance by using the `--disable-openapi` flag:

+```bash
+mint dev --disable-openapi

 ### Preview as a specific group
 
 If you use partial authentication to restrict access to your documentation, you can preview as a specific authentication group by using the `--groups [groupname]` flag.

 ## Formatting
 
 While developing locally, we recommend using extensions in your IDE to recognize and format MDX files.
 
 If you use Cursor, Windsurf, or VS Code, we recommend the [MDX VS Code extension](https://marketplace.visualstudio.com/items?itemName=unifiedjs.vscode-mdx) for syntax highlighting, and [Prettier](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode) for code formatting.
 
 If you use JetBrains, we recommend the [MDX IntelliJ IDEA plugin](https://plugins.jetbrains.com/plugin/14944-mdx) for syntax highlighting, and setting up [Prettier](https://prettier.io/docs/webstorm) for code formatting.
